3 topics across all disciplines.
From isometric to installed line — fabrication, erection and testing
How to read a piping isometric, why spool breaks decide what happens in the shop and what happens at height, and the test and reinstatement sequence that gets a line handed over.
Pressure test packs and reinstatement — the gate, and what gets put back afterwards
What a test pack contains and why it is built as the work proceeds, the procedure and the calibrated gauge, the falling pressure that is temperature rather than a leak, and the reinstatement register that is what actually keeps a tested system honest.
Electrical commissioning and turnover — from dead to live
Why insulation testing needs electronic devices disconnected and readings corrected for temperature, what a functional test proves that a settings check cannot, why an inhibit register exists, why as-left settings are recorded, and what changes the moment a system is energised.
